RS51.1-4G-031-D-NN-FW/S150

The RS51.1-4G-031-D-NN-FW/S150, Bosch Rexroth Indramat, RD 500 Drive Controllers unit integrates high-precision speed control into a compact enclosure. It operates on a nominal connecting voltage of 3-phase AC 380–480 V and delivers a continuous rated power of 31 kVA to high-speed grinding spindles. Encased in an IP20 housing, the converter is engineered for installation in industrial switch cabinets. Rugged design and optional firmware modules provide precise motor regulation under varying load conditions.

Designed as a Device type: Drive control device for high-speed grinding spindles, this drive incorporates a Built-in brake chopper and resistor for safe energy dissipation during deceleration. Input power is accepted at a nominal connecting voltage of 3-phase AC 380–480 V with an Input frequency range of 50–60 Hz, while the Output frequency range spans 0–2000 Hz for flexible speed profiling. The unit draws a Rated current of 52 A at full load and supports dual-channel serial communication via Interfaces: RS232 and RS485. Conformal coating and an Ambient temperature range of 0–40 °C ensure reliable operation even in harsh plant environments.

Seamless integration with plant automation is facilitated through standard serial links and configurable parameter sets, minimizing commissioning time. The drive’s robust brake chopper and resistor combination enhances reliability by safeguarding against overvoltage events. Ideal for grinding, milling, and high-speed spindle applications, the RS51.1-4G-031-D-NN-FW/S150 delivers precise torque control and consistent performance across demanding industrial processes.
